What is Triaminicin (acetaminophen/chlorpheniramine/phenylpropanolamine)?

Acetaminophen is a pain reliever and a fever reducer. It is used to treat many conditions such as: headache, muscle aches, arthritis, backache, toothaches, colds, and fevers.

Chlorpheniramine is an antihistamine. It blocks the effects of the naturally occurring chemical histamine in the body. Chlorpheniramine prevents sneezing; itchy, watery eyes and nose; and other symptoms of allergies and hay fever.

Phenylpropanolamine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces the blood flow to certain areas and allows nasal passages to open up.

Acetaminophen/chlorpheniramine/phenylpropanolamine is used to treat nasal congestion; itchy, watery eyes; itchy throat; sneezing; headache; fever; and other symptoms associated with allergies, hay fever, and the common cold.

Phenylpropanolamine, an ingredient in this product, has been associated with an increased risk of hemorrhagic stroke (bleeding into the brain or into tissue surrounding the brain) in women.
